yes i know
this diffusor is letting more air through
thats all
the flame likes air
if he gets it right , then the engine will realy like it.
good job
 
Hi Christian, nice to see you here! Good looking diffuser you made there. I have a similar diffusor for the KJ66 drawn in autocad, not tried yet. Did you simply extend the existing original wedges or did you change geometry slightly? Curious on how you calculated outflow area.

Best regards,
Gerald
 
ciao Gerald...

i simply extended the original wedges...like your drawing (the cnc radius is according to the tools available)
i added n.3 hole for bearing cooling.......an reworked the compressor cover to reduce gap
then all seem to be good.. :-)
